We are scientists!

We've been working on our scientific skills by keeping a lab book. We write our observation,
question, hypothesis, procedure, results and conclusion about different things. The above lab was about snow and how it can change its form into a liquid by melting (duh I know). I had the girls fill out their lab book and make some guesses as to how long they thought the two cups of snow would melt on the counter and also in the fridge. (We put two cups in there as well.) They also guessed as to how much water would be in the cup after the snow melted. There were some good guesses.
I was actually surprised that this snow, which was light and fluffy, melted into about 1/2 cup of water. It took about 2 hours for the snow to melt completely on the counter in our 63 degree kitchen and about 7 for it to melt completely in the fridge. Good work girls.
